Nighthawk M1100 Mobile Router with Google Fi SIM card?

[scottran]

We're trying to set up a hotspot on our google fi account; google fi sent us a data only SIM for the purpose but it doesn't work, and actually doesn't seem to fit the slot.  Is there an adapter that we need?

MR1100 uses Mini SIM. If Your Google Fi SIM is a nanoSIM, you need to find a adapter to use with MR1100.

Right now, most of carriers provide the 4-in-1 SIM cards. Please refer to the image attached
